hi!! welcome, we're so glad to have you here ^^
all essential information will be revealed as the fest moves along, but to give you a little rundown of what to expect: on the 18th 00:00 KST slickfest will open prompting, which means that a form will be posted for slickfesters to submit their prompts/ideas; this will close on april 25th 00:00 KST (slickfest always operates according to KST, so we'd recommend checking how that translates to your timezone!) and, after that, mods will make a masterlist with all collected prompts that will become available for viewing and perusing on the 28th! if you find a prompt (or several!) that interest you, claims open on may 1st at (you've guessed it) 00:00 KST: a claiming form will be posted and in it you will be asked for the prompt codes (that you will find in the masterlist) of your choosing and to state your first, second, third, etc.. (up to five) choices, this is because claims operate on a first-come, first-serve basis, so in the event that a prompt of your choosing is already taken, you will hopefully have other choices to fall back on!

you will then receive an email to let you know which one of your choices you've received — authors may only write one prompt at a time, so we recommend that you really consider your prompt priority when submitting your claim! the masterlist will then be updated to mark the prompts that have been assigned and those that are still available and it will remain open to viewing all throughout the writing period! if, at any point, you realize that your choice isn't working for you anymore, you may contact us to drop your prompt and switch to another available one (or drop out of the fest altogether) ^^ in the event that available prompts are not what you're interested in, slickfest also offers the option to self-prompt! if you'd like to know more about that, you can check out our more thorough answer here: self-prompting.
the submission deadline will be on november 1st 00:00 KST, after which (at a TBD date) reveals will begin, all works will be posted in small batches and will all be initially anonymous! but more information about that will be given once closer to the writing deadline ^^

we hope this answers your question, if you'd like to know more please do not hesitate to send us another q or contact us on any of our platforms!
