Scroll down using the scroll bar on the right to find the right option for you. 

The most commonly selected options are below.

If your manuscript was invited as part of events at a SICB annual meeting, then select from the options: symposium article, symposium introduction, complementary session, student award paper, awardees (such as Gans, Morse, Moore, Bartholomew) .

If your article was invited outside of being part of an event at the SICB annual meeting and is not part of a larger collection of articles, then select 'invited review' for review papers or 'invited paper' for research articles.

If your manuscript was invited as part of a special issue, then keep scrolling down beyond "complementary session" and select the name of your special issue. The screen grab for this guide shows three such special issues ("BIMS", "Global Changes in a material world", and "Pearse invited").
