yes fucking brilliant that skype thingy is for IM & audio between up to 5 persons I believe?
even enables chat/im behind most firewalls/tricky configurations
for HTML/web editing I never quite found the killer application so would be interested to hear what you guys use?
Netscape/Mozilla got a decent WYSIWYG editor & so does MS with OE or frontpage, which can be good to track links etc. for a complete web site.
html-kit is good for HTML editing & checking your code or even converting 'old' html to xhtml supporting mobile lite browsers
