i worte some "replace" code for my blogger system, its a piece of code that hase an encode function (used when submiting the blog entry) and a decode function (used when reading the entry for editing); at the moment i stopped with few things: something about colors like [red]...[/red], some site specific links (linking easily to another user page), smileys conversion; i sttoped it because many people know how to use html and if i use a ubb code, people using html wont find their html code when editing a saved entry, but the decode function will give them back the "ubb-like" code; asnyway if you are interested in my code, just let me know, with few changes you can implement html totally!
