Welcome to the new members. The forum is now opened to registration. Only so the forum can grow, expand and be better. The new members must behave and follow the rules. It is up to you for how long the registration stays open.
I am also curious. While I welcome the new members and the potential for new content shares from them (not to mention "likes" on my shares that have been around a while) I am a bit hesitant as there is still an issue with what appears to be someone reporting links for Mega takedowns as well as the leaking of high-quality content that originates from here. I have no answers, nor criticism of staff and mods...I appreciate you and all the work involved. Personally, I'd just rather not see the flood gates open wide.
There isn't a fixed number of members or a fixed closing date for registration. I too wish that only good members will join, but time will tell.
