Every forum site don't allowed to user create a link, i don't know what reason is behind this.
The reason is quite simple: prevention of spam. If a forum would open a possibility to any new user (generally, a guest
) to put hyperlinks, all moderation efforts would be done to cleaning off such messages each day. Because 99% of messages containing hyperlinks, are not related to the forum contents at all. So basically, on each forum, including miniBB forum, there is a strict prevention of posting hyperlinks - a member should prove s/he is posting a related content; and we also strictly limit new members on posting new messages per day. I suppose, if you came here just to post a message with an unrelated hyperlink, you have 0% of chances of it being posted kept.
