The disadvantage of allowing guests to post is that, the quality of posts/content may be poor. For avoiding this problem we are taking these steps:
- Guest posts wont appear instantly. WinMatrix staff will approve them.
- Old threads won't be dug up, unless the post is very important.
- Any post which doesn't contribute something useful to a discussion thread won't be approved.
The reason for allowing guests to post is that, here a lot of members post just once and never come back. I don't want to fill our database with them. Moreover, if a guest feels to post again then I think he would be encouraged to register instead of filling the CAPTCHA again and again.
