We currently have 48 questions tagged dual.
There questions are on different subjects:
- Dual ISPs
- Dual dual mail accounts
- Dual monitors
- Dual graphics cards
- Dual boot
- Dual OS installations (installation, time synchronisation, ...)
I suggest to retag a few of them (e.g. to multiple-monitors, multi-boot) and to burn the tag because it is way to vague and does not add anything to the questions.
