Occasionally I'll need to administer my team's users and projects in TFS, which usually results in me having to annoy Jonathan our TFS guru at Esendex and beg him to help me. It's not just me that finds it difficult to administer TFS users and projects though; Microsoft don't make it easy for us developers at all.
Luckily, some nice people over at Attrice Corp have made it easy. Introducting Team Foundation Server Sidekicks, a GUI tool for TFS admin tasks.
You're welcome :)
