Oy, I had to look up TLA. A three-letter acronym that stands for....three-letter acronym. ....That seems confusingly redundant.

Couldn't that also be interpreted as a two-letter acronym?

Ten Letter Acronym! Does anyone know of one instead of random letters?

OMGEDBICTR!

Ex Astris, Scientia.

Wish the forum had a built in text expander that replaced all the acronyms with the actual set name and number.

Ten Letter Acronym!

Or twenty or thirty.

Oh my god Epic Dragon Battle is continuing to remain?

How did you get that? I could only get Oh my God Epic Dragon Battle. The rest was a mystery to me.

I honestly have no idea what the ICTR is. My first guess was actually "is counting towards retirement" but that sounds off just the same.

What is f5?

What is f5?

 

F5 is the standard keyboard key that can refresh your browser.  Sometimes when retailers get low on stock, folks will F5 (refresh) over and over to see if it pops in stock as orderable.

to be complete: 

 

With the recent realization of how to read the date codes on the box seals I thought it could be of some value if we had the known codes listed in one place. If anyone pays attention to this thread could a MOD who enjoys playing with Excel (Grolim) make a table?

It appears as if the codes on the box seals can be read as follows
45R4 where 45 is the 45th week of year ending in a 4 or 2014.
The meaning of the letter is still unknown at this time.

 

Not sure if it evolved since then. We know what the letter means?
