Hello SueMy advice would be to get away from Outlook Express ASAP. Why? Cos as your list gets bigger, managing subscribe/unsubscribe requests could turn into a big job..
If you have access to CGI on your web site and a little tech know-how (or can get it), then this may be the best option. There are lots of scripts (of varying quality) floating around to manage lists. The downside is for really huge lists (thousands'n'thousands of people) is that it can eat into your bandwidth allowance (your host may charge you extra if you exceed it), and puts extra work on your server, which your host might not like. For small + moderate size lists, particularly if not mailing daily, this should be okay.
Alternatively there are quite a few windows programs floating around to do opt-in list e-mailings. I am not sure how well they deal with the management side, which is the main issue going forward
We tend to use scripts for our lists, except for the smaller lists, where it's easier to use listbot etc.

As for conversion, I think cut'n'paste may be your friend. See if you can figure out a way to cut'n'paste int whichever program/solution you eventually use.
If the Outlook Express won't easily cut'n'paste into the correct layout for the program you're converting too, sometimes it helps to use an intermediate program, a bit of testing and trial'n'error might find the answer. For example you might find that cut'n'paste to word or excel, reformat in word or excel, then cut'n'paste to the final program works.
Good luck
