Thanks for letting me know about the broken link. I don't think we need a special forum for that. Such things can be mentioned in this forum or in the forum for the specific topic like it would have been ok to ask questions or make comments about skinning documentation in the skinning forum or localization documentation in the localization forum or developer documentation in the developer forum etc.
I don't really want to ship more skins especially since I don't maintain the rtl skins. It would be better if you have a page on the Persian community site, then I can change it to link there, or if you want we can make a page on this site in the skinning documentation section about rtl but it should link to the zip of rtl skins that you are maintaining.
