Léacslann is being retired and replaced by Lexonomy, a new web-based system for writing and publishing dictionaries and other collections of structured data.
If this is your first time here, go to Lexonomy instead and see if it meets your requirements.
If you are an existing Léacslann user, consider migrating your data to Lexonomy as soon as possible. Léacslann will continue being available until at least the end of 2016, but will be taken offline at some stage after that. If you need help exporting or migrating your data, contact us.
