In effort to help new users find the best content in the forums over the years, I want to begin compiling a list of the community's best/most useful/must read threads and posts.

I've started a bit by compiling a short list of the best guides/how-tos from that section which I've put below, but want to make a more extensive list of the top threads overall. If you can help contribute, please reply to this thread with links to other threads you think should be included in the Best Threads/Must Reads for new members.

Blindfold Solving Tutorials:

Tools:

History:

Methods:

God's Number:

Group Theory:

Algorithm (Lengths?):

Big Cube Theory, Formulas and/or Calculations:

FMC:

Optimization Topics (Besides God's Number and FMC)

Miscellaneous Puzzle Theory (and/or Math-related) Topics

Great start here to the list of the most useful threads. Does anyone have any other good ones? This one I'll add as well. Lets keep this building and I'll update the main thread with the complete list of suggestions.

I am not asking anyone to agree with all of the threads in the following list, but at least it could spark a few ideas (from the older members). I would have added parity algorithm threads (since that is/was a hot topic), but I covered that in the Wiki. (@pjk, you can look there in external links to retrieve some that you liked, if you want. Also thanks for adding my cubing contributions thread. That reminded me to update all of the broken links in my contributions post!):

The Older Cubers Discussion thread is now approaching 1000 pages. It is currently heavy on blind solving tips, but in general welcomes anyone, tending to be around 40+ (I'm 80), but anyone 25+. A very encouraging bunch that helps newbies, but also goes deep into advanced stuff. Made me feel part of the community, and they got me to enter my first comp last month.

Will add it to the list, thanks!

@pjk, I apologize, but I grabbed all the threads from my previous post and put them in this post with these additional threads, as some of them are in the same "category" as the new ones (which I forgot to mention before).

Again, these are just my opinion. So add only the ones you want. There's no pressure to add any of them, despite that I know almost everyone will at least agree that one of these should be considered in this selection. In addition, they are not in any particular order.

Excellent, much appreciated. The plan is to have a sticky or page with the most useful threads so people can easily start reading and learning from the best of the community. If you have any others, please reply here and I'll update them over time. Many of the best threads are years old too, so there may be more to be said and discussed now. Feel free to continue the discussion if you have further thoughts.

If anyone else has any suggestions, please post them.

I've updated and formatted the original topic and added more threads. If you suggest another format or other posts to add, please let me know. This is a good start and will be useful for people looking to read some of the best threads on the forum.

Maybe put each group of threads in a spoiler? That would make it easier to find what you what quicker

Good idea. My only concern are the current categories - do you think we should reorganize or leave them as is?

Maybe put all bld ones in their own category, seperate from sighted tutorials. Also that cubing vocab thread has like 2 things lol.

I went ahead and put things in spoilers, but BLD into it's own, and removed the vocab link. Thanks for the suggestions, if you have others please let me know.

Sorry for the bump, but I believe this is a truly useful and very helpful thread.

Good idea!
