My group has been using Skype for years now. Aside from it adding the
ability to record sessions, over time it has been getting worse, not
better - less able to adjust stuff, refusing to let you change the app's
window to certain sizes and shapes, etc.

MapTool
EpicTable
Obsidian Portal
Astral

And if  you need a digital character sheet, here's one that looks pretty cool: http://rpgsuite.com/

If it were D&D, you could add tools like:
World Anvil
Fantasy Grounds
Roll20Pro
Scabard

I've realized though that all I want is an audio app, something that lets me have a map with fog of war and some ability to move character and NPC tokens, and someplace I can define rolls. I would like to be able to have separate messaging to group and individual players. And a log. And audio log might be nice too.

Some of these tools tend are tied very closely (despite what they say) to a particular type of game (D20, D&D, usually). Some have character sheets that can do a bunch of work for you (generate, have automation that does calculations, etc). And some let you layout your entire campaign like a mind-map or with a lot of other interesting concepts.

My issue is: In almost every case, if I do a lot of work building my world on their product, they can cease operations and there is no useful way to get my data out. If I can get it out, it certainly will need implementing into another type of site or tool which will never just be 'take form one, load into the other with a click'. And if I want to implement house rules in character creation, in custom careers, in combat rules, in task difficulties, etc.... I'm outta luck.

I miss Kloogewerks and I miss Grip iPC and iGM. The latter had tools that I used to build deck plans. When I specified a roll to go a player with that, I sent something like roll a pilot check and the character representation for Traveller allowed them to click and a 2D6 roll + Pilot skill roll would show up in the chat from that player. That's all the automation I ever wanted. I haven't seen anything as Traveller-centric and as flexible today without being a much more overdone and constraining framework.

I'm just going to do my documenting and tracking of games on my own web pages and on a forum which uses an open source forum software so I can have my own. Then I never have to worry about a company going kaput or not being able to afford my subscription.

I'd keep using Skype, despite it's problems ( It's bandwidth heavy, some of its code goes back to another product prior to Skype and that's why it is hard to modify and add features to), but it does the audio part okay. It was more useful when it let 3rd party plugs ins run to record to MP3 (then I had audio session logs and I miss that as a ref trying to remember what everyone did or said) and I miss that capability. I just haven't found a better option that lets me keep an MP3 audio log as we game to replace it yet.
