Does my site warrant a new category ?

I'm having trouble finding a category for my site - <url removed> .

both
Regional: Europe: United Kingdom: Business and Economy: Shopping: General Merchandise
&
Regional: Europe: United Kingdom: Business and Economy: Shopping: Gifts

Seem to be for Retailers who SELL gifts.

Shopping: Gifts: Gift Registry
Appears to be for sites where you register & set up a WANTS list (like a wedding list)

In my opinion, GiftGen doesn't fit any of these.

I've also tried searching for 'Advice' , but that seems to be more used for personal advice (e.g. teenage pregnancy councelling)

Would there be a possibility of a new category for Gift Ideas or Suggestions ?

Not likely.

Submit to the single best category and use the description area to note that you think a new category is warranted.
the reviewing editor(s) will determine if a new category is warranted -- but it is exceedingly rare for a new category to be created for a single site.
