Currently there is a tag hp-pavillion aimed at HP Pavilion laptops; this tag is actually misspelled. I've tagged my question Regular audio corruption when listening to music with hp-pavilion, but can't link this tag to the main one, nor correct the typo in the original as I am unable to suggest synonyms.
As an aside: why is the rep requirement for merely suggesting a tag synonym so high, especially compared to that for suggesting edits to posts? Intuitively I'd have thought people would have to wait longer to edit others' posts than to edit tags, since tags seem to be a relatively minor thing but a careless edit could completely change the meaning of a question (I've seen a couple of edits around that have changed the title of a question so that it then asks the exact opposite of the body, for instance)
I understand the point brought up elsewhere that people should understand the system before being able to make changes, but to my mind that should come down to those reviewing suggestions rather than the people making them, surely?
