Is is just me, or does the board/server seem to edit my codes? Like, I want to put up a certain font and have multiple colors, and then when I hit 'preview' it changes everything to one color (usually the first color listed) and then uses the default font for the board I'm posting in, and changes all of the other tags to closing color tags. It only does this sometimes, and I know I'm coding my stuff right, because I'm versed well in both HTML and BBCode. If tis happens to you, how do you fix it?

It's a very annoying issue that IF has, yes. But it can (usually) be avoided by careful coding. If you start a list, ALWAYS close sizes before you start it, and put the new size inside of the list tag, and close the new size tag before you close the list. Example:

I also believe that, whenever possible, the code also seems to like color tags to be inside of size tags.

thanks so much! I was starting to wonder if maybe my particular board had something against making things complicated....

That's another one of the many reasons why I host my own stuff and don't use IVF.
