My Little Forum provides a number of BB-Codes. One has to activate the conversion of BB-Code in the forum settings with setting bbcode to 1. This enables a set of basic BB-Codes for formatting text and insert links in the entries with an additional linktext. Some further BB-Codes are hidden behind additional settings.

For some of the BB-Codes the forum software provides a UI to insert them in the posting text. The UI provides the necessary buttons and displays them beside the text area to insert the posting text. There is currently no similar UI for the signature form.
