Hmmm...Thats something only the mods has power over. You're talking about like a locked sticky thread? Because if I make a topic with one lone post, that'll sink to two pages away in about a week and it might be forgotten.
We just need one good clean thread so the mods can see that its worthy and possibly ''Stick it''. But these threads can be used as a brainstorm until someone gives the right direction.
It doesn't have to be a sticky (that would definitely be best though), just whoever makes the first post would be the custodian of the thread and keep all the suggestions collected into the first post periodically for easy reading.
The same thing that we have here except everything gathered into the first post instead of somewhere along the line in the thread. You could even take everything from the last post I made in this thread collecting everything preceding it and just add it into the first post in the thread you made a few days ago and go from there.
A good clean thread like you said.
