This plugin is no longer necessary for most users because similar functionality has been integrated into b2evolution's core. For more information, please see: Autolinks Plugin
AcroLink lets you build a list of keywords that become either acronyms or links. If you use it for links you also get a title tag with your link. The list of keywords is maintained in your back office - there is no need for editing external files. The plugin settings allow you to specify which blog(s) it applies to, and who can add to or edit or delete keywords from the list.
