the slightly smaller rotunda

Here’s some of the tools/methods I use:

• Instapaper - Absolutely shit-hot way to get through a high volume of articles/blog posts/what have you. When viewing a page in your PC browser, just hit ‘read later’ and then suck it all down to the Instapaper iPhone app before you get on the tube. Can have folders too (so it’s where I store recipes too for easy access in the supermarket). Costs a couple of quid, but absolutely worth it.
• Google Docs - I keep my main action list here (divided into columns for this week/next week/sometime/personal lists). Also loads of client docs - WIP notes etc that I want to keep adding to.
• Tweetdeck - best twitter for desktop hands down for managing multiple accounts and searches.
• MindManager Pro - my mind-mapping app of choice (but can be a bit expensive - there’s free versions such as XMind that come close).
• Tumblr - bunch of ways different people use, but I use to clip & bookmark quotes & stats & interesting PoV.  (Although Delicious remains my heavy-lifting bookmarking service.)

None of those are revelations (perhaps), but all are extremely useful.

I’m re-assessing how we share knowledge and stats and info best in our corner of the agency at the day job.

My requirements are below - please let me know if you know of something that fits the bill, or comes very close:

• Has wiki functionality AND forum functionality
• Doesn’t have to be WYSIWYG editing, but can’t be all scary text-based markup to do the formatting and linking
• Has good backup capabilities - and of both the forum and wiki components, not just one
• Ideally using some sort of format that could be ported to another provider without too much hassle
• Is either not a per-seat license model, or a cheap per-seat equivalent  (more than happy to pay something, definitely not expecting something for free or ad-supported)
• Ideally hosted somewhere, but could be self-hosted without it being a deal breaker
• Can have new info added in via email - either to specific pages, or to a collective ‘inbox’ page where people can then take and move to the best page or spot
• Can have individual pages opened up to be public and not hidden behind a login/password  (or, to have those pages grouped as different access level).

Know of any services fit the bill?    Here or @andrewpascoe47   
Much appreciated

FYI, I’ve used Wikidot before, and it comes close - but fails on the export of forums part (& not sure about the common export format part).
