My account is on sopuli.xyz, and both while logged in and not logged in, i have seqrched for my user name, my comments, and posts. I have done the same with lemm.ee (i also have an account there). I have searched on other instances while not logged in. All have yielded nothing.
I am subscribed to a number of mtgzone communities with my sopuli account and regularly see posts there, both by members of mtgzone and other instances.
So there is some content making it out. I am wondering if maybe three nature of my account creation caused an issue, a corrupt account maybe? When i signed up initially i botched entering my email address and was never able to complete registration. I created a second account and you or Andrew changed the name or something, it has been a while.
I tried to log into the second account a while back to test that theory and was unable.
I opened in October 2018, the first set I carried was Rivals of Ixalan. They are still in my system as $3.99/pack. While Lost Caverns of Ixalan, iirc the last set before Play Boosters, is $4.99 for Draft, and $5.99 for set.
There was one official price increase since I opened, but we also had price changes going from Boosters —> Draft/Set —> Play. MSRP for Foundations Play Boosters are $5.25, while Aetherdrift are $5.49. I am guessing Tarkir will be the same as Aetherdrift.
