Notes:

Inconsistent searching. What's the rationale behind having an awesome, scaling, global search and still, years after it, we are performing forum searches, glossary searches, data searches, user searches. Whenever possible/available... all them should default to global search, with same options/wildchars... consistency (and performance!)
