The LKFF forum use a system similar to UBB to allow you to include links, images and smileys in your posting. UBB looks a bit like HTML but is much simpler; you cannot use HTML in forum postings.

Smileys

For now, smileys are disabled

And if I want a link or something special in my post, how should I do that?

In this forum you cant use HTML because of possible abuse of the features offered by HTML. You can use UBB-code to format your posts. The codes you can use are:
[b]bold[/b]
[u]underline[/u]
[i]italic[/i]
[quote]quote[/quote]
[strike]strikout[/strike]
[url]http://www.lkff.nl[/url] for a simple url.
[url=http://www.lkff.nl]Loz Kampos Fragging Force[/url] for a nice url.
[inturl=news.php?nid=849]Presenting the new website[/url] for a direct link within the website.


And... pictures? How do I do that?

Also with UBB-code: [img]http://www.provider.landcode/user/picture.jpg[/img]
Make sure the picture is on a good webserver! A link like C:\My Documents\Directory\Picture.jpg will obviously not work.
Also please keep in mind that your pictures should not be -huge-. Else you will mess up the layout of the website and an admin will delete your post.
