Well to address your issue regarding a "master post", assuming you don't want to mess with the coding of this forums to much. How about make a master sticky topic that does two things.

1) Gives a link to a web page in the pocket legends general website that displays all the guides and a link to each of them, along with a brief description the title, last time it was updated, author w/e else you want. All this can be done via a database usage for example (or what ever way you see fit)

2) Assuming this goes via route info is entered into a database to be used for part 1) have a link to a website that lets players enter the link of the guide (the guide must be on the forums) and a description. From their right a script that gets the author of the post, when it was made, last time it was updated, title and so on into the database.

Granted after thinking about it, i'm sure a database isn't needed and can get the info of the entered link and add it to the master list webpage directly, but I understand it more with using a database as the idea so im leaving that in the suggestion.
