I've noticed a "redmine" tag showed up this week. Is this usefull? Will we have a specific tag for every PM tool out there?
I think that we should allow tags for PM software (not least because so many questions are about MS Project!) but I'm not convinced we need one for each and every version. For example, we have tags for ms-project, ms-project-2013, ms-project-2010, ms-project-2007 and project-server (the last of which should really be renamed 'ms-project-server' if it's going to remain).
I'd suggest that where significant differences exist (like between MS Project Server and MS Project) then two different tags can exist. Otherwise they should be merged.
I believe there should be a "pm-software" tag, but I also think it's okay to have specific tags for each tool.
Each question can have up to 5 tags, so we have plenty of room to grow and break things down.
