Probably, but not necessarily. It might depend on whether individual guests charge me. I should point out that the site is free to you, but it most definitely isn't free for me (I pay the bills out my own pocket and I am far from rich), nor is it free for the rest of the staff who put their time and effort into making the entire site happen, or the other volunteers who contribute in many ways to Songstuff. I am sure you ask "will these be free?" with the best of intention, but sometimes it is worth reminding people that someone always pays.
There are differences between song lyrics and poems. Lyricists are not poets, and vice versa. I have known many experienced poets who have much to learn about being a lyricist, though I grant you many skills and concepts are transferable and they may find writing for some genres fairly straight forward. The mere fact that lyrics are intended to be only part of the finished piece, that they create a song only by being in combination with music, complicates the whole picture. The whole being greater than the sum of the parts and all that. I point this out to make sure that you are familiar with song forms, lyrical hooks And other song mechanisms. Songs are most definitely not poetry, though some songs are poetic in nature, many are not. I am sure you are very familiar with meter and the many different types of rhyme as they are the same essential concepts as poetry. If you are as familiar with the specifics of the requirements of songs, and the nuance of combination with music (even from the perspective of being a lyricist) great, but I would rather highlight these differences at a stage that you can change what workshops you take part in if necessary.
