I'm trying to say, "If anyone wants to meet up, please let me know" as a general invitation to a group of my friends.
Is this correct? もし誰か会いたいなら、声をかけてください。
I'm unsure if my usage of 誰か is correct in this situation.
Although not necessary, I'd also appreciate it if the invitation sounded casual. Do I have any other options besides just ending the sentence in 声をかけてね？
