This is an index of all the puzzles that have taken place in the LG15: The Last web series.
Following her video The Gold Coast, Antonia appeared to be having fun in the north, and responded infrequently to members. On March 21, 2009, she posted a message to her Twitter account, stating "I need help! Please! It's the only way to get the message through!!!"
A new photo gallery on her account was quickly found, entitled HELP ME!!!. The gallery contained three separate images, each displaying Egyptian hieroglyphics.
There was a long-winded search for the solution that occurred over the weekend, following the discovery of the puzzle. Most glyphs remained mysterious, although the flight number QF 925 was determined. On Monday, Antonia updated her twitter account, stating that the intended meeting time was Tuesday.
An official solve was eventually given, by Antonia herself. 
They Must Be Stopped!!
Using simple substitution, the code was solved to be "SEE, PETTY FOOLS LIKE YOU WILL WASTE TIME CHASING RED HERRINGS... LIKE THIS".
She soon followed up that puzzle, with another:

Again using simple substitution, the code was solved as:
WELL DONE ON THE LAST ONE NOW WE'RE HAVING FUN HERE'S A CLUE WHAT'S ONE KEY THAT CANNOT OPEN A DOOR?
Stop the Celebration
With the video Stop the Celebration, Sibylla placed a Vigenère cipher in the video description.

The key for the cipher remained elusive until Sibylla returned to comment following the release of the video Sounds of Silence, stating a fascination with Australian spiders. The key was later determined to be "Atrax Robustus", the scientific name of a common spider found in Australia. Using the key, the cipher was quickly solved. (It should be noted that the ultimate solution contained a few curious typos.)
