I posted to a "friend" on a MB using a free web proxy (German). I agree with many posts here re: proxies - really not necessary, however I used one because this MB displays remote addresses. After my post, someone posted (blank w/o message) using the same proxy IP. Stupidly, I posted back to "friend" to say that was not my blank post. Surprise - my real Ip showed up! At that same time a "test" notation appeared in the upper left of my screen. Also at the precise time an IP on my LAN (my IP is random for each internet access) appeared on my firewall log. Was this a spoof attempt to gain access to my computer? or was someone trying to uncover my real IP on the MB for amusement? After paying closer attention, I thought I detected a very slow connection at the proxy stage w/o showing an address for the MB. Thoughts always appreciated.
