I just noticed that there is a tag atlassian which doesn't really servera purpose, since Atlassian isn't a single product, they produce a lot of products. There are tags for some products:
Usually tags like this start with the company name, like microsoft-excel or google-compute-engine, so I was about to start replacing these tags with atlassian-fisheye and similar tags, when I realized that it would most probably be much easier to just rename those tags.
Could someone with enough reputation just rename these tags?
Afterwards I would start retagging the remaining 41 questions just tagged with atlassian with tags that refer to the actual product and write up some descriptions for those tags.
