Barry:

I am one of the first members of the Yahoo Colon Cancer Support Group.

I lost my husband to colon cancer about 1 1/2 years ago and have

posted intermittently since then.

I also read some postings from time to time. I just read a posting of

a Roriae? I have read a lot of posts and I question whether he is a

legitimate colon cancer survivor. I think that he sounds like a very

disturbed individual. I hope that you are not listening to his posts.

I think that the best way to handle him is not to reply to his posts.

I am not posting this on the site because I do not want to encourage

more of his bizarre posts. I hope that, in time, he will stop posting

here and go elsewhere.

All the best,

Amie

Becky: I am in agreement with you and Annie. There are any number of avenues

available for many of the problems that seem to spill from his cup. Several

groups

in that area,patient advocates, can provide help on many fronts. Now I read

and delete

We made an effort to reach him,let him know he might be contacted and left it

up

to him. I still say a prayer that if he is sick(ill) he will receive help.

Becky,

I checked the name in my yahoo mailbox and hit the spam button after

the first couple of posts.It doesn't have any affect on the board

postings but at least they no longer come to my yahoo mailbox.
