great for DBs which support t-sql stored procedures :-)

If you wanted to do it all in SQL you can try the following. I would write
it as a stored procedure and call that but you might be able to do it in a
cfquery. The trick is that if you select into a variable and the select
statement will have multiple rows the variable assignment happens for each
row so you can effectively append to the variable.
declare @lnUserid int,
@lcUserName varchar(50),
@lcComments varchar(8000),
@lrFinalComments table (userid int,
username varchar(50),
comments varchar(8000))
declare UserList cursor fast_forward
for select userid, username
from users
open UserList
fetch next from UserList into @lnUserid, @lcUserName
while @@fetch_status = 0
begin
set @lcComments = ''
select @lcComments = @lcComments + comment + '<br>'
from comments
where userid = @lnUserid
insert into @lrFinalComments
values (@lnUserid,
@lcUserName,
left(@lcComments, len(@lcComments) - 4))
fetch next from UserList into @lnUserid, @lcUserName
end
select * from @lrFinalComments
