I've summarised and compiled most events conducted in Sri Lanka, or related to the usergroup, in the annual report linked below. If you are aware of relevant events which you would like to include, please do feel free to add to the report.
The report for the past fiscal year closes on 17th February.
If you need any assistance, do reach back and I'd be happy to help!
