3. It should be noted that supporters should not be used as a general operating term for people who create or partake in CRTs. I'm not necessarily a Garfield or a Garten of Banban supporter and yet I have participated in a CRT for the former and made a CRT for the latter. Also, I'm pretty sure that most of the time the staff who do show up in CRTs may not be supporters, especially when it comes to smaller verses. I personally try and avoid pushing CRTs onto staff members not because I don't want them concluded (I do; it just takes time), but because I personally feel I'm just bugging them if I were to do so, which I feel isn't right. This is bearing in mind that I've actually seen calc group members being okay with posts on their message walls (as noted in the "New Rule to Help Calc Group members") thread, yet in no place have I seen staff bring up being okay with posting CRTs on their walls. There is a CRT promotion thread, but ennh... I still have days left before I can post something new there.
And no, out of what little experience I have, being staff myself does not boost the signal.
