what library is this?

[eluser]jairoh_[/eluser]
1. how to add something like this in the site? or is there a library for this?



2. how can my site read html tags like bold, qoute, code, anchor and etc? because it queried text content from my database w/ those tags, but those tags were ignored.

3. how can html automatically know if the text was a link, or automatically creates an anchor tag if the text is a link


i need help. tnx
