Looking for two plugins!

Hey all

I’m looking for two plugins, one of which I’ve used before but can’t for the life of me find it now.

#1 – A del.icio.us plugin, which allows for custom options within the WP Admin; to specify account details and such, and having the links showing on whichever page you want with a bit of code. The main part is that it had the Option settings within the admin panel.

#2 – Not sure if one exists, couldn’t find it in the Codex. Basically, to automagically replace acronyms such as AOL, MSN and encase them within an acronym tag and have the info for it.. if you get me? 🙂

Any help?
