HomeSite Add-On's List
Check around. I'm sure you'll find something useful.
Note that many add-on's listed under ASP Classic are useful for
multiple languages and for generic HTML development.
Disclaimer: I haven't made most of
these extensions myself, so I can't fully vouch for their functionality or
quality beyond the limited testing I have done with each. You'll have to
discuss details with their authors. Please let me know of any problems too though.
