On some other post I read where you are going to provide a mod to incorporate the users database so wwwthreads and linkssql can share. This is a great thing. If the two programs could be searched together would be wonderful also. (since I use both)
I noticed that the Links website does this. The two programs just blend together...
I believe this would be a very happy and successful marriage!
Did I also read somewhere on this site about you developing a chat program?? If so the combination of the above three would be very interesting. I saw what everyone.net does (or is it everything.net?? I'm confused) with this concept and I was not impressed. I think you could do a better job on a bad day.
Anyway, just wanted to add my two cents (inflation adjustment=$10.98) worth.

Keep up the good stuff.
