I think it comes from the time when LazPaint did not have his own subforum. In Third Party forum..
That could explain it, but that isn't the case any more, yet everybody still keeps posting to this single thread - like we are doing now. :-) Yet more variation of discussions - all under one topic.
Using a newsgroup maybe it's ok, I don't know how much people will read the newsgroup vs read the forum (for example I will keep just reading the forum) just because I'm used to using forums, nothing more.
Don't you read emails? Don't you use mailing lists? If you do, you could use a Mail/News client combined - like Mozilla Thunderbird. All electronic communications in one applications. That's convenient.
Either way, I don't care to much. I just thought it wasn't the best idea to throw every topic under the sun, and the kitchen sink under a single
LazPaint (alpha-blending, antialiasing, filters) topic. That doesn't make sense to me.
