The link problem

I have use this code "url]http://url[/url] or [url=http://url]URL text[/url" to link to other website, however, when I click the links it go to strange site? "http://10a5class.forumotion.com/go/aHR0cDovL3d3dy5tZGZyLz9mbHZtbm5lanN5cg=="

yeah looks lil out of whack.

what is the link?

or just use this.

Code:

[url=yourlink here ] your text or image here(IMG TAGS FOR IMAGE)[/url]

for example:here is my forum http://10a5class.forumotion.com/forum-f9/topic-t211.htm
I creat the link [url=link]mediafire[/url], but it appears "mediafire.com 4xxgtmtydqw". Besides, the link didn't connect me directly to the website....

Yes forumotion has made it like that, there is no way to change that.
