The NRL's new community rugby league competition and participant management system, MySideline, is up and running, with over 2000 participants already registered.

The improved online product will service upwards of 1200 clubs and 120 leagues around Australia, making club officials' lives easier.

After about 2000 administrators were onboarded to MySideline and taught how to use it in face-to-face sessions in recent months, participant registrations opened on Tuesday night to a great response.

"Years in the making and due to the hard work of so many people, it is exciting to launch MySideline," said NRL Digital Service Manager, participation Andrew Banasik.

"Having 2000 registrations in the first day is a great start to an exciting product."

Three-and-a-half million registration records dated as far back as 15 years have been migrated from the old system to MySideline.

Survey responses to MySideline from over 300 administrators so far have been positive, with the site boasting a 4.2/5 rating for ease of use.

Almost 90% of surveyed administrators said they had the knowledge and skills to perform key tasks in MySideline.

"That shows the system is intuitive and is starting to meet the requirements of the rugby league community," Banasik said.

"This is just the start. There's a lot more functionality to come in the coming months and years and that will be built on the needs of the community and participants."

All parents and/or participants will access MySideline through an NRL Account – meaning only one sign-on is required for all rugby league products.

And the system is good for the pockets – reduced payment processing fees mean $3.35 is saved on a $150 transaction per participant.

Clubs are also able to sell playing and training gear through MySideline, further simplifying the sign-up process.
