Hi,
Regarding "support once question", I want to use this phrase for BBS. Sometimes you find a good topic in a BBS, and support the topic starter. Can I post " Supporting once" or " Support once" ?
I wonder if you mean the impersonal pronoun 'one'? ie one's onstead of once.
eg When one expresses an opinion, it's nice when people support one's comments.
Best wishes again,
Clive
