I've seen similar things on various forums. Some don't think it's a good idea to highlight cross posters; some don't want any links to other forums; still others don't want any offsite links. My view is that forums are made up of volunteers offering help/advice to those posting questions/issues/problems and help can be in many forms including links to other sources(forums, sites, articles..). I like to think, and try to confirm, that a poster has given an honest effort. There are those that just want someone to solve their problem while they show no interest, no effort and minimal interaction. And there are some that just want to rant or complain.
I have been criticized and warned about providing links to other forums and now rarely go to Bytes --even though they have some great info.
Suffice to say each forum has a range of participants, participation and culture -- but AWF is more tolerant and helpful than most.
