I am the developer of Skribbl.io Helper, and I\'ve just updated the script from 0.12 to 0.20.\nThis new update allows for multi-language support, but your current WORDLIST will be affected!\nPlease transfer your current wordlist to wordlist[Lang] so Skribbl.io helper can use your current wordlist.\nSee this this forum (greasyfork.org/en/forum/discussion/48865/) for more information and how to transfer!\n\n This popup will stop appearing once the transfer is complete.');
