I noticed this too, and asked about it here, but no replies <img src="smileys/smiley1.gif" border="0" align="middle">.
@Tom, is there some option you can enable in the forum software, so we can opt to have it changed back to how it was? (i.e. we go to our profile page and tick the check box saying "notify me of replies to threads where I reply" - or the like). Or to at least be able to subscribe to threads (and get alerts for new posts). Or, better still, both <img src="smileys/smiley4.gif" border="0" align="middle">
