I think the problem comes when you don't know the word for the thing you need to search. Someone on moddingway recently put up a post about his line textures not being smooth on the corners of the models in his game. If you do a search on this forum for "line textures not smooth" you get tons of hits where something was said about lines, textures or smoothness. But, it's really tough to dig through all of those threads to find one that really covers what it is you're looking for.
If they knew the word aliasing or anti-aliasing, they would get this this thread as the second hit:
http://www.soccergaming.com/forums/showthread.php?p=3783714&highlight=antialiasing#post3783714
which has tons of great information in it. How many people who barely speak the language know the words aliasing or anti-aliasing. Or even, "jagged."
I know we have tried an FAQ before and it didn't work terribly well, but it seems like what we need to do more of is
1. Provide a central location where answers are stored.
2. Encourage people responding in the community to either link to where in the FAQ the person can find their answer OR at least encourage the person to use certain search terms.
Anyway. This is a soapbox issue for me because I've spent hours on forums like this trying to self-teach coding. If you don't know the search term you really need, you can end up getting very stuck (searching) for a very long time. Then when you finally do post, you get slammed for not searching. This forum especially can really be brutal.
I hope that's a fair response? For what it's worth, I think I misunderstood initially what you meant by putting all the explanations in one thread. Sorry for that misunderstanding. I think it will be fine if we can help people a little more with how exactly to search for what they are looking for.
