Whooo bit of bashing
bring it on..lol
Seriously,I see everything is free to download on here,I see support where and when it can be given publicly.If you allow members to take things to pm,not only do you kill the thread as no one ever returns to show how it was resolved, so your potentially wrecking the site.But also your taking away the learning side of things.
If your not willing to share,because you had to learn yourself,then keep it to yourself.There will always be someone with less morals who will share the info.
Then again I suppose the site could become subscription only, and then the what you know and not willing to share wouldn't happen.
