I have written the following on my poster: Special thanks to: "Professor Name" and "Professor Name" for their support through out this project, my numerous colleagues, #1, #2, #3, #4, #5, #6 for their assistance during lab work and last but not least to my parents "Dad" and "Mom" for their support through out this journey. Is this good enough? I am not sure if I should actually write the names of my parents and whether I should list all the people who shared tips and tricks with me in the lab. For the latter, is there a general rule to follow for people who helped me with lab work, i.e helping me only mixing concrete. Can I just list first names when thanking colleagues to save space? Thanks!
