First I guess we need to find out if the purge has gone ahead?
Then I would suggest coming up with a specific set of tags to use in each board, so we can then go about tagging threads... anyone have an idea how many tags we are looking at to keep the number manageable but also so searches can be specific enough? I mean I guess that will vary board by board but nothing wrong with having a base limit to work with.
In terms of how we get it done I reckon we should have groups of people working on different (broad if we have few people) sections, a) to stop people overlapping with work and b) so people have a clear direction where to head.
How does that sound?
Oh and also what are people's thoughts of having an index recording which threads have been tagged so we know not to go over them? It may take a bit more effort when going through and tagging but should save work in the long run.
