Hi,
It may not be an issue over the points, but it might still be a good idea to send a reminder, and if ignored - name and shame.
I sometimes take a few days to find out that I have a request filled, but [hopefully] I tend to reply quite quickly with points.
If it an older request it can mean trying to locate the original request and find out what i offered, but still should be fairly quick, and I will still send these even if I notice the item has already been posted.
This is a site whee we are supposed to be supporting each other [although a few more filled items could be posted, even if no more high points offered].
Lets keep the sharing going and provide that support - but equally, let everyone know who is not on-board with the rest of us.
