is scrapbooking a gerund?
i remember being taught that
fishing as in "joe went fishing today" isn't a gerund, but
fishing as in "NO Fishing" was.

the difference being a gerund has the quality of "a continuous state of being"
joe wasn't fishing yesterday, and might not being fishing tomorrow, so fishing, wasn't for joe, a continual state of being.

but the NO Fishing sign meant no fishing today, and there was no fishing permitted yesterday, and no fishing would be possible tomorrow.. fishing was not permitted continually.

you might be involved in scrapbooking in your free time, or on weekends, but i doubt you are continually working on your scrapbook..

still me getting involved in fine points of grammar and parts of speach is not a good thing.. i'll stick to my knitting.
