I think it would be useful to have a tag relating to AGA cookers, and possibly another one relating to AIMS (Aga Intelligent Management System).
Due to my reputation I can't suggest/create one myself.
Let me know your thoughts.
After this question being marked as a duplicate, I want to mention that I only followed the advice from this Stack Exchange post about tag creation.
The answer quotes:
As an alternative, you can request creating a tag by starting a new meta discussion. This gives other people the opportunity to discuss if a new tag is needed.
Since I thought this question was adequate for an open discussion, I thought it would be appropriate to post in on meta site.
